Coffee Water Footprint for Water Management in Dak Nong, The Central Highland of Vietnam

Abstract

The Dak Nong province is in the Central Highland. The natural condition of its land, soil and climate that well supports to coffee cultivation. To grow one coffee crop, it requires much water for irrigating. In rain season, irrigated water is from rain water. And, in the dry season the irrigated water is from surface and ground water. The current changes of climate caused the long dry season with high temperature and low rainfall in rain season. These have strong impacted on coffee cultivation and production. This paper applied the methods of remote sensing and GIS in the water footprint analysis by CROPWAT model to identify the crop evapotranspiration, water footprint, blue water footprint, and green water footprint of coffee farming in Dak Nong province. Then, the conclusions and suggestions for water resource management and protection for proper water using and sustainable development of this province
